The 1995 hit from Oasis' seminal LP '(What's the Story) Morning Glory' might be one of the Britpop group's biggest songs - penned by guitarist and chief songwriter Noel Gallagher - but the band's former frontman still hasn't mastered the chords.

However, his 16-year-old son Gene - who he has with ex-wife Nicole Appleton - is well ahead of his famous father with his strumming.

Liam told The Sun newspaper: "I don't even know how to play it on guitar man, that is the joke.

"My kid can play it, but seriously, I can't."

The 'Some Might Say' singer - who also has daughters Molly, 20, and Gemma, four, from flings with Lisa Moorish and Liza Ghorbani, and 18-year-old son Lennon Gene with former spouse Patsy Kensit - says Gene is keen to follow in his footsteps and form a band.

He told Australia's Herald Sun: "Gene's still in sixth form but he's desperate to be in a band. He plays guitar and drums, he's on the look out for band members."

Asked what is singing voice is like, Liam said: "I've not heard him sing, but he's got the attitude and the look for sure. He's a good little guitar player, he's better than me. I mean, I can't play, but he's good."

The outspoken rock star says he'll continue playing 'Wonderwall' no matter what because the its what the fans want.

Liam - who is currently on tour and promoting his debut solo album 'As You Were' in Australia - explained: "I heard that, it topped some Triple J poll didn't it? But it's a big song everywhere around the world.

"A lot of people give it a bit of stick, they say they've heard it a million times but as soon as you play it people lose their sh*t over it and they're all f**ing buzzing.

"The way I see it there's a new generation of people coming to see me or (brother) Noel (Gallagher) and they want to hear it.

"They've paid money so who am I not to play it? I don't mind playing it. I love it. We play it with a cello and an acoustic guitar now, I think that's how it should be done. We'll be playing it in Australia, don't worry."
